Go for it Tony
I tell you the results really are amazing. Before I started I would come home to a solid film of grean algae that I would have to scrub off daily, now a week and 2 days into zeo there is nothing, just a few litte spots here and there. My water has also gone from having a yellow colour to it, to being white and clear.
I actually just moved some of my new SPS pieces down in the tank becuase they were starting to burn becuase the light is penetrating deeper in the tank.
